Quick Answer
While minimal shelter can increase survival challenges in cold climates, it is not impossible to survive for short to medium periods. A person can survive with minimal shelter for 3-5 days, depending on clothing, fuel, and available resources.
Choosing a Shelter Site
When selecting a shelter site in a cold climate, look for areas protected from wind, such as a group of trees or a depression in the ground. Avoid areas with standing water or where water may accumulate. In a survival situation, choose a site with a south-facing slope to maximize solar heat gain.
Building a Shelter
Use available materials, such as branches, leaves, and pine needles, to build a lean-to shelter or a debris hut. Aim for a sloping roof to shed snow and rain. In a cold climate, aim for a shelter that is at least 6 feet (1.8 meters) tall and 8 feet (2.4 meters) wide to allow for standing room.
Staying Warm
In a survival situation, maintain a body temperature of at least 95°F (35°C) to prevent hypothermia. Use techniques such as huddling, body heat sharing, and fire starting to stay warm. Aim for a daily caloric intake of 3,500 calories to maintain energy and body heat. In extreme cold, ration food to minimize energy expenditure.
